Patent JP-S5851775-A (JP)
Title: Voltage type pulse width modulation inverter
Inventor: ANDOU CHIHIRO
IPC: H02M7/48
Filed: 1981-09-24
Abstract: PURPOSE:To automatically adjust the decelerating time for variously varying load states by providing a decelerating time limiter. CONSTITUTION:A DC line voltage which is supplied to an inverter is detected in a voltage detector 10, and when a DC line voltage rises, and the decelerating time setting of an input limiter 2 is switched through a decelerating time switching circuit 11, thereby switching the gradient of the output voltage line to low gradient one. When the line voltage abnormally rises, a signal synthesizer 8 is driven by a signal from the detector 10, thereby breaking all transistors T1- T6, and driving an abnormal time signal output circuit 12 to trip a contact 13. Thus, the input voltage of the inverter is interrupted.

Abstract: PURPOSE:To synchronously update distributed sites by alternating two-phase COMIT with a simple data check n accordance with message recovery and data contents. CONSTITUTION:Indoubt indication is added to data sent from an application program M to an application program S1; and when th application program M issues PREPARE, the application program S1 returns ACK in case of normal processing but returns NACK in case of abnormal termination. Log is added to these responses. When responses to PREPARE are returned from all slave nodes, the application program M sends COMMIT request with log if processings are normally terminated in all of these nodes, but otherwise, the program M sends ABORT request with log. When COMMIT/ABORT request is received, the execution of a slave-side application program S2 is started, and the indoubt indication of corresponding data is erased in case of COMMIT request, and the corresponding data is restored to the state before update in case of ABORT request.

Filed: 1977-12-21
Abstract: PURPOSE:To repeat the terminating through a simple circuit until the connection with the idle circuit is over or the busy state is identified for all circuits by repeating the terminating in succession in case the terminated subscriber is busy. CONSTITUTION:Relay NU1 operates in case a call arrives and the subscriber is busy or when the connection is desired so that the terminating is given to the predetermined subscriber. In this case, if the subscriber who receives the terminating is busy, relay LFP is actuated in order to actuate relay LB1 and to release the storage position information and then to release relay CK. At the same time, relay FP is released with release of the subscriber position information is released. After confirming these release, relay NU2 operates to release relay LB1. Thus, the terminating connection is given newly to the next subscriber. As a result, the terminating can be continued until the end of the connection with the idle circuit or the identification is given to the busy state for all circuits.

Abstract: PURPOSE: To secure uniform cooling and to produce heat-treated pipe of excellent quality, by detecting the position of four or more points on the circle at which the cooling of steel pipe starts by means of industrial televisions, and by controlling the position of cooling nozzles in order to make the circle cross the pass line at right angles.  
     CONSTITUTION: At four points on a circle where the cooling of steel pipe 22 starts are arranged industrial televisions (ITV) 23 at an interval of 90°. When hardening is normal, i.e., cooling-start line 3 crosses the pass line at right angles, the cooling- start line is regulated so as to be located at the center of each ITV 23. In such situation, the hardening of the steel pipe 22 is monitored. When cooling becomes abnormal, i.e., cooling-start line 3 inclines to the pass line, red-hot part decreases at the upper ITV 23 position and increases at the lower ITV 23 position. The nonconcentric state in arrangement of the steel pipe 22 and cooling nozzles 1--- is indicated as a relative slippage of cooling-start line and is distinguished easily.
